Re^2: Executing a string as a Perl command
in thread Executing a string as a Perl command

... and this is better than my $var1 = 5;
my $var1 = 5;
The question was simply how to get it to execute once it was set. The answer is eval.
If the user gives you some form of # rm -rf * ~ / , a lot of your files get deleted
If you want to run arbitrary code supplied by a 100% trusted source at runtime, what would you use other than eval?
Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
